AttributeError: NullTranslationsBabel instance has no attribute 'isactive'

How to Reproduce

While doing a GET operation on /admin/general/plugin, Trac issued an internal error.

Ubuntu 14.04, apt-get installed trac 1.0.1 (as is the default), genshi 1.3 (as is the default),

just enabled the accountmanager plugin (apt-get installed, default version), and everything gone black. :)

​http://trac.edgewall.org/ticket/10903#comment:5 applied by hand (yikes), trac still fails.

14.04 is an lts version, so I don't want to tweak anything, just use it as is, as long as it is. If there must be a backport, please patch the 1.0.1 or update the package in the ubuntu repo. Thank you.

A duplicate of #11345. That has been fixed in 1.0.2.
